It is said to be one of the few surviving wood framed lighthouses left on Lake Superior. The complex includes a square tower rising up from the attached Lighthouse keeper's quarters, a brick fog signal building, frame barn, brick oil house, boathouse, two outhouses, and a dock.[4]
The old battery system in the fog signal building was replaced by a solar powered 300 mm Tideland Signalacrylic optic atop a pole, which continues to light the island to this day.[5] The location is an active aid to navigation, with a characteristic white flash every 2.5 seconds.[6]

Access
Most of the Apostle Islands light stations may be viewed (but not accessed) on the Apostle Islands Cruise Service water taxi or by private boat during the summer.[7] During the Annual Apostle Island Lighthouse Celebration[8] Ferry tour service is available for all the lighthouses. In the tourist season, park rangers are on the island to greet visitors.[9]
